What TutorLingua is

TutorLingua is a tutor-led language learning product. Tutors invite learners they already work with, assign focused practice, and use homework evidence to plan the next lesson.

This policy describes the founder beta and paid tutor billing path as of July 2, 2026. It is written for tutors and learners, not only lawyers.

Account and relationship data

We collect account details such as name, email address, authentication identifiers, selected role, and profile settings needed to sign you in and show the right product area.

When a tutor and learner connect, we store the relationship, route, language defaults, invite state, and homework assignment records needed to run the tutor-led workflow.

Homework and progress evidence

We store challenge attempts, answers, outcomes, completion status, and tutor review notes so learners can continue a session and tutors can see useful lesson-planning evidence.

Tutor review evidence is teaching support. It is not a certification, exam score, or replacement for tutor judgement.

Speech practice and pronunciation

Speech practice requires learner consent before assessment. If consent is not present or is revoked, TutorLingua blocks provider scoring and evidence persistence.

When speech scoring runs, we may send the expected phrase and learner speech to a pronunciation provider. We keep structured pronunciation scores and verdicts for learning evidence. Raw provider payloads are kept for up to 24 hours, then cleared by a scheduled database purge.

Payment and billing data

For paid tutor plans, Stripe collects and processes payment method, billing address, tax ID, invoice, receipt, and subscription details. TutorLingua does not store full card numbers.

TutorLingua stores the Stripe customer, subscription, checkout-session, webhook, plan, allowance, billing status, and entitlement records needed to open Checkout, manage access, reconcile invoices, respond to support requests, and audit billing changes.

Support, email, and operations

Support messages can include account, privacy, safety, tutor, learner, relationship, homework, or email-delivery context. Privacy and safety reports are priority-marked for admin handling.

We store email delivery events, support thread status, admin audit records, and product failure events so a founder or admin can diagnose signup, invite, homework, and support issues without asking users to debug the system.

Website analytics

The public website may record simple pageview analytics and performance signals so we can understand whether launch pages load and route people correctly.

We do not sell personal data, serve advertising, or track you across unrelated websites.

Founding-tutor email list

If you submit your email through the “Get the founding-tutor letter” form on our tutors or pricing pages, we store it with Resend so we can send founding-beta updates. Submitting is optional and separate from creating a tutor or learner account.

You can unsubscribe at any time using the link in any such email, or by emailing support@tutorlingua.co. The “Book a 20-min founder walkthrough” link on those pages opens Calendly in a new tab; TutorLingua does not receive anything from that click beyond you scheduling a call.

Tutor applications

If you apply to become a tutor from the “Apply to become a tutor” form on /tutors, we store your name, email, tutor profile link (for example a website, Preply/italki profile, LinkedIn, or Instagram), and any notes you add, so the founder can review your application and verify your tutoring background.

We keep application records, including declined applications, for review history and audit even if you are not approved or do not proceed, and to detect duplicate applications and prevent invitation mix-ups. Approval sends you a signup invitation email; a decline is never auto-sent — if the founder replies, it comes from them directly.

You can ask us to remove your application data at any time by emailing support@tutorlingua.co.

Service providers

TutorLingua's current subprocessors are Vercel for hosting, runtime, analytics, Speed Insights, and AI Gateway when enabled; Supabase for database, authentication, storage references, and scheduled database jobs; Resend for product email and the founding-tutor email list; Stripe for checkout, billing, tax, invoices, and subscriptions; Sentry for scrubbed error monitoring; OpenAI and Anthropic for enabled AI, grading, and speech-generation features; Azure Speech for enabled pronunciation assessment; and Calendly for scheduling founder walkthrough calls when you choose to book one.

Those providers may process the data needed for their part of the service. Stripe handles payment and billing data for paid tutor plans. Sentry events must be scrubbed before leaving TutorLingua and must not include raw emails, names, tokens, support bodies, speech payloads, Stripe payloads, Resend payloads, or SQL errors.

Data rights, retention, and deletion

Some records are retained while an account, subscription, or tutor-student relationship is active because they power homework, billing, review, support, audit, and safety workflows. Raw pronunciation provider payloads have a shorter 24-hour retention window.

You can request a data export, factual correction, retention explanation, or account deletion from the account page or by email. These requests are handled through TutorLingua support, not instant self-serve automation, and are routed to priority privacy/data support review.

Deletion review covers active tutor-learner relationships, homework evidence, billing state, support messages, email events, speech consent, tutor application records, and retained audit rows before we confirm what can be deleted, retained, anonymised, or deferred. Support and admin operators use the admin subject, email, billing, and support tooling rather than ad hoc production SQL.

If a tutor and learner are in different jurisdictions, or if a guardian is making a request for a tutor-managed learner, include that context in the request so we can verify authority and review the correct obligations before promising a specific outcome.

Children and tutor-managed learners

Paid self-serve launch is intended for independent tutors working with adult learners. TutorLingua is not intended for children under 13. Tutors should only invite learners when they have the right to do so and can explain the tool to the learner or their guardian where needed.

If a tutor-managed learner or guardian has a privacy question, contact us and include the account email and your relationship to the learner so we can route and verify the request safely.
